In this cooling device, air cooling, air-jet cooling, mist cooling, water spray cooling and spray cooling from weak to strong from are took. This paper tells us that how to design mist cooling device, and I make a example of mist cooling device for us. During the design of mist cooling device, I make full use of the soft of FLUENT, so that the design can meet our requires. This thesis consists of parts as follows: 1. The device in the design is used to cool the mold steel of 5-150mm thickness, 100-850mm width and 2000-8000mm length. The aerosol cooling equipment is used for cooling the thin mold steel plate. In order to meet requires, I make a optimal design of the aerosol cooling equipment. Many results of FLUENT are compared, and I choose a better solution from them. Then I need to design size of the aerosol cooling equipment. 2. Then the Nozzle spacing of the aerosol cooling equipment should be designed. I need to manufacture a GAMBIT model about it, and import this model in FUENT. In order to save time and simplify the calculation, we need to make sure that the model is simplified. We must do a lot of experiments, and find a better design that can keep mold steel uniform cooling. Aerosol cooling system design methods and utilization of the die steel quench has a certain reference value research.
